"I listened intently to the plan of possible action as Lane outlined it to Sands. Allie's father explained that at a certain time the guards at the only avenue of escape would be changed and the mechanical Jovians with their tentacle-like arms, controlled by a remote central, would be put in their places. Lane explained how he had previously located the source of control over the mechanical men and was therefore, perhaps, in the position to disconnect the controlling system and suspend their activity. This sounded like a very excellent plan, but how, I thought, would it be possible for us to steal near the central control apparatus in our attempt to disconnect it? Surely, the Jovians must maintain a constant guard over such delicate and important apparatus. But on the other hand, they may not feel a need of it in view of the fact that Allie Lane and her father had been with them so long that they accepted them as being harmless. "At any rate, Sands approved of the plan and it was decided that the attempt to escape would be made at a time when Lane was to give a low whistle and we would all meet in Allie's chamber, providing, of course, that the way was clear. Lane, with his forefinger, drew an invisible outline, showing the tunnel through which we were to go. Sands watched him closely and absorbed the information. Meanwhile, I shot rapid glances around the chamber in its entirety in my part as guard. Several times my heart jumped when I heard sounds that softly broke the stillness of the cavern, but the sounds failed to bring what I expected--the grotesque Jovians. "Sands was standing in the center of the room now, Allie Lane in his arms. They kissed endearingly. Allie's father paced the floor nervously. Suddenly Lane stopped pacing and faced his daughter and her lover. He opened his lips to say something, thought better of it, then turned half away. He swung around presently as though he had decided on some question confronting him, and spoke softly. "'Allie,' his words, nervous and tense, reached me. 'You love, Bob, don't you dear?' "'As well as life, father,' she answered. Sands turned to look at Lane, puzzled. "'Suppose, then,' Lane returned, 'that you marry Bob now. It would be a good thing in the face of whatever confronts us.' "'I would marry him now, father,' Allie said in a half whisper that I barely caught. 'But how?' "'You forget, my dear, that I was a minister back in Kansas City,' her father smiled. "'I've waited a long time, Allie,' Sands put in, holding Allie's shoulder and looking into her eyes lovingly. "'Then I will marry you at once, Robert,' she said, her eyes shining with happy tears. 'Father can perform the ceremony.'
